The voltage produced by a Josephson Junction is proportional to the frequency of the applied microwave signal. This is known as the Josephson effect, where the voltage across the junction is directly related to the frequency of the electromagnetic wave. The Josephson effect is a quantum mechanical phenomenon that occurs in superconducting materials, and it is used in various applications such as high-precision voltage standards and superconducting quantum computers.
